After Android 10 update, LED notification do not work anymore. I did Factory Reset - not helpfull. I booted phone in Safe mode - not helpfull.
I discovered, it has some connection to EdgeLighting. If Edge Lighting is Off, LED notification is not working at all.
If EdgeLighting is On, than for supported apps by EdgeLighting, LED is working, too (ex. Viber, Messages...), but it doesn work for Missed call.
I have the same problem now. It doesn't work anymore after a few reboots and there is no way to solve this problem. This is an update bug and samsung must fix it !!!
Shame on Samsung .. such bug should not take place in a business phone for 1000 euros or should be repaired immediately !!!
The Latest phones do not have an LED. I am pretty sure the latest phones use Edge Lighting.
Becase new phones do not use the LED. LED support WAS NOT INCLUED in the Android 10 Update.
I reported this issue and Samsung is aware of it. The More we complain about it the more apt (I hope) Samsung will work on it.
This is a maintainance issue for Samsung. This is to keep old phones working. Of course, what most large companies are concerned with is what make money for the next quarter. This means the accounts that get the funding are new product release. We have to scream bloody murder to get our 'old' devices working.
I had a security update in early April, but this didn't fix the issue. If you had an update on Sunday, anyone else and I who hasn't received this update yet will get this soon which will fix this issue.
